20 PCS Marker Pen Tips Replacement for BOOX Pen Plus, Pen2 Pro,Max Lumi2,Note Air2,Note5,Nova Air C Stylus,Triangular Pen, and Softer Round-Shaped Stylus Tip, Nib (20 PCS/Black)

Work perfectly at a good price.

These work fine with my tablet, but they seem to wear down a little quicker than the nib that came with the pen originally.

I bought it for my Lenovo Smart Paper , Perfect fit

普通に使えた！ コスパ最強！ 追記 １部のペン先で誤作動が起きましたが、ペンからペン先を少し浮かせる（最後まで差し込まない）と使えました。 ニッチな内容はChatGPTに聞くのが良いですね。 純正品よりもスラスラ動くため、書き心地が変わることには注意。自分の用途ではあまり気になりません。

I had just bought a Boox Note Air 5C and started to learn how the tips on the pen worked. I realized I was going through tips at a rate of about 4 weeks per tip. So I went to find some off-brand tips. This was the best recommended one at the time, and it was 20 for ~$15. They work just as well as the original tips. Maybe even a little better. I plan for this set to last me at least a year and a half In fact, it's only been a week, but the first tip seems to have lasted longer than the brand-name tips. I wonder if this set will last me 2 or 3 years. I didn't realize how useful it would be to have the extra little ring that comes with it. It's good to have an extra one of those, in case the one that came with the Boox tablet goes missing. It makes it very easy to change out tips at will. I don't know all the difference between all the different kinds of tips you can get for a Boox tablet EMR pen, but this one has been exactly what I was looking for: something just as good as the brand-name, if not a little better, for very cheap.

The feel isn't the same as the Boox pen tips, it feels like sliding across glass rather than the paper feel the original provides. I could live with that if it wasn't for the fact that as soon as the tip touches the tablet, it will continue to track up to almost an inch away when the pen is lifted from the tablet. It makes writing impossible as the pen "never leaves the paper" and results in an illegible mess. The tip is also slightly larger than a Boox tip and while it will fit, after switching back to the branded tips, they no longer fit as tight and can slip out with little force, looks like I might be ordering a whole new pen as well.

Delayed but product was as advertised. I would buy again.
